Our stay was near perfect but there's a few blemishes which I'll mention later.
We're not Thai but frequent visitors to Thailand over the last 20+ years. Having stayed at many areas of Bangkok, Ratchathewi is our choice as it is dead in centre of town with many restaurants and good massage shops right around the corner. Iconic shopping centres was one BTS stop away. Though we preferred walking to combat extra calories we've taken in.
We thought it was a misprint when Patty said the access to the BTS station was 3 metres. It wasn't a misprint. The front gate was literally that close.
The gates were guarded by security personnel who saluted us on each passing. The apartment is accessible via access card and keys. We felt very secured.
The apartment was as in the photos and as described. It's modern, new and clean.
We gave the bedroom to our elderly mother to enjoy while we tested Patty's sofa bed which folded out in the lounge room. It was comfortable.

The large glass sliding door facing the pool, street and BTS station below. This gave us vast air space in front of us offering good city skyline view. The easterly aspect gave plenty of light but the double curtains did a very good job when light was not wanted. The car and train noise was audible but not an issue at all for us.
The apartment was equipped with two air conditioning units, two large flat screen TV and washing machine. WiFi was fast and never failed during our stay. The kitchen was well stocked with usual appliances and utensils. We conveniently cooked our own breakfast.
The venetian blind in the bathroom was not openable. I offered Patty to fix it but she did not response to this. Little did she know that I run a company making blinds in Australia. Perhaps she did not want to bother her clients.
The apartment has more than met our expectations.
Patty was very kind and responsive in communication. We talked at check in like long lost friends. We did not require her help exploring the city but could sense that new visitors to Bangkok would find her an asset. She kindly offered to let us store our luggage at her nearby guest house. Her husband Sony came to assist.
The blemishes, we had a couple: there's no toiletries provided and the towels were a little thin. These little things could have completed the feeling of luxury complimenting the modern apartment. We could not find any major faults or issues.
We look forward to our return stay.
